Abstract: A solar concentrator for concentrating solar radiation toward a solar cell, a concentrated photovoltaic module including a solar concentrator and a solar cell, and a secondary optical element for use in a solar concentrator are provided. The solar concentrator includes a primary optical element for collecting and focusing the solar radiation, and a secondary optical element. The secondary optical element is arranged to receive the solar radiation collected and focused by the primary optical element and includes an input end, and output end, and an adiabatic light guide tapering from the input end toward the output end and configured for concentrating and adiabatically guiding the solar radiation between the input and output ends. Some embodiments of the present invention can be useful in solar photovoltaic applications where it is desirable to provide high acceptance angles while maintaining high concentration and optical efficiency levels.

Abstract: A method for associating a mobile electronic device with a preexisting subscriber account includes capturing a matrix barcode image presented on a display by a first device. The matrix barcode image is encoded with first device identification data that identifies the first device. The first device identification data is associated with a preexisting subscriber account stored in a subscriber database. The method further includes extracting the first device identification data from the matrix barcode image, and obtaining mobile device identification data that identifies a mobile electronic device. The method further includes transmitting a message to a device manager server, the message including the first device identification data, the mobile device identification data and a request to associate the mobile device identification data with the preexisting subscriber account associated with the first device identification data.

Abstract: A U-shaped spacer element supporting and retaining a photovoltaic panel assembly spacedly over a rooftop corrugated sheet; one shorter side leg thereof having an oblong bore, the other side leg having an intermediate ridge section. A screw engages into the ridge web and axially clears the shorter leg, anchoring the main body to the supporting rooftop frame elements through the corrugated sheet. The ridge section conformingly abuts against a longitudinal rib of the corrugated sheet. An L-shape bracket inner leg abuts against the main body short leg, the bracket outer leg abutting sideways against a registering portion of the photovoltaic panel assembly. A second oblong bore is made into the outer leg and extends parallel to the plane of the main body base leg. Two bolts engage the oblong bores and adjustably interlock the L-shape bracket to the spacer element main body and to the photovoltaic assembly.

Abstract: An automatic transmission for a linked chain driven wheel includes a plurality of chain-engaging sprockets disposed coaxially with and spaced apart along the axis of rotation of the wheel. Each of the sprockets has a predetermined diameter which differs from that of the other sprockets. The sprockets are drivingly connected to the wheel. A chain guide, which is axially movable relative to the sprockets, is provided. The chain guide, when aligned with a given sprocket, will guide the drive chain into engagement with that given sprocket. A chain guide actuator is operatively connected to the chain guide for varying the axial position of the chain guide automatically in response to the angular speed of the wheel.

Abstract: An automatic transmission for a bicycle comprising a sprocket wheel of variable diameter, for receivably engaging a linked bicycle chain, drivingly connected to a bicycle wheel. The diameter of the sprocket wheel can be varied in relation to the angular speed of the bicycle wheel. Variation in the diameter of the sprocket in response to drive pressure applied by the linked bicycle chain is prevented by a locking mechanism.
